Adaptive Predistortion Using a Delta Sigma Modulator for Automatic Inversion of Power Amplifier Nonlinearity
This brief demonstrates a new adaptive digital predistortion architecture particularly suited to mobile handset applications. The central idea is to build a lookup table (LUT) that directly captures the static compressive nonlinearity of the power amplifier (PA) and then insert this LUT into the fee...
